General Description
The MicroLink 101-0032 is a USB to HART® protocol modem featuring standard
DIN rail mounng. It provides the hardware interface between Highway
Addressable Remote Transducer devices (HART) and a Windows®PC with a
USB interface.
MicroLink is used for commissioning, diagnoscs, monitoring, and tesng HART
field devices. Communicaons direcon control is handled internally so there
is no need to control tricky request-to-send (RTS) handshake ming, greatly
simplifying soware development.
Virtual serial port drivers allow the USB MicroLink modem to appear as an
RS-232 com port to Windows and your HART soware for increased
compability.
The DIN rail mounng clip is compable with widely used 35 mm EN 50022
rails. It can be snap mounted and removed from the mounng rail without tools
for quick installaon and servicing. A status LED provides confirmaon of the
transmied and received HART packets to help you quickly troubleshoot your
system and verify operaon. Power is provided by the USB port so no external
power supply is required.

Driver Pre-Installation
The USB drivers should be installed before the MicroLink HART modem is
connected to the PC’s USB port. Aer the drivers are installed, Windows will
automacally detect the modem when it is connected to the USB port and
complete the setup.
To pre-install the drivers, run Msetup.exe
from the included CD. The CD will auto-run
this file if the Windows autorun feature is
enabled for your CD drive.

Install USB driver before
connecng to the USB port.
Important!
Click the Install buon in the 101-0032 window to pre-install the USB drivers.
The driver installer will guide you through the setup process.
Installers can also be run manually from the CD, without running Msetup, by
running \x86\dpinst.exe file for 32 bit operang systems or x\64\dpinst.exe for 64
bit operang systems.
Don’t have a CD drive?
Download the HART Protocol CD image from www.microflx.com/pages/support
Running the file will self-extract the compressed files and
start the Msetup.exe HART Protocol Setup Ulity.

Finding the Assigned COM Port Number
When Windows installed the serial port driver the next available COM port
number was assigned to the converter. The soware you use with the converter
must be set to use the same COM port number. To find the number assigned to
your converter run Msetup.exe ulity from the CD and click the Com Port List...
buon to show a list of found devices and assigned COM port numbers.

MicroLink modem is assigned to COM 7
To use the list...
Unplug the modem from the USB port
and it will be removed from the Com
Port List.
Plug the modem into the USB port and
it will be added to the Com Port List.
Set your HART soware to use the
same COM number assigned to your
modem.
Uninstalling the USB Drivers
If needed, use Windows Device Manager to uninstall the driver from your
system. With the modem connected to the USB port, locate the MicroLink
modem in the Device Manager hardware tree under Ports (COM & LPT). Right
click on MicroLink HART Protocol Modem and select Uninstall from the pop-up
menu. When the process has finished, unplug the modem from the USB port.
Driver inf file - Manually Installed
To manually install the driver inf file...
1. Connect the Converter to the USB port.
2. Open the Windows Device Manager.
3. The New Device Wizard will have added the converter under
Ports (COM & LPT) and will appear as MicroLink HART Protocol Modem
(COMx). Right click the device and select Update Driver SoŌware...
4. Choose to Browse for the driver soware and browse to the CD or the
locaon of the MxHART.inf file.
5. Follow the wizard prompts to complete the driver setup.

Click OK to use the new port number and close the window.
Unplug the MicroLink modem from the USB port and then re-connect it to
allow Windows®to update the USB device parameters.
Click OK again to close the Properes window.
Windows Device Manager
The assigned serial COM port
number can be changed to any
available COM port using Windows
Device Manager.
Expand Ports (COM & LPT) in the list
to see which port the converter is
assigned to.
Right click MicroLink HART Protocol
Modem and select Properties from
the pop-up menu.
On the Port Settings tab, click
Advanced.
Drop down the COM Port Number list
and select the desired port number.
Using Windows Device Manager
The assigned COM port number can be found using Windows Device Manager.
Open Device Manager and select View > Devices by Type.
You may need to expand the Device Manager tree under Ports (COM and LPT) to
see the converter.
In the example shown below, the modem is assigned to COM 7.

Connecting to the HART Device
Connect the two screw terminals to the HART device or HART loop. Microlink
provides electrical isolaon between the HART loop and the PC. It is safe to
ignore grounding and polarity issues when making the HART connecons.
The HART protocol requires a loop resistance of 230 to 600 ohms, typically
250 ohms. Refer to your equipment installaon instrucons for details on
connecng a HART master or configuraon device to the loop.

Status LED Operation
When the modem is connected to the USB port with drivers installed, the status
LED will be green indicang that the modem is ready. The LED will be red while
transming or sending a packet to your HART protocol device. The LED will be
orange while receiving the HART reply.

Software Setup
Make sure your HART soware is set to use the same serial COM port number
that the MicroLink modem is assigned to.
There are no hardware sengs required by the MicroLink modem and modem
power is provided by the USB port. All other sengs, such as BAUD rate and
parity, are taken care of by your HART soware.
